The Flatiron District is a neighborhood in the New York City borough of Manhattan, named after the Flatiron Building at 23rd Street, Broadway and Fifth Avenue. Generally the Flatiron District can be said to be bounded by 20th Street, Union Square and Greenwich Village to the south; the Avenue of the Americas (Sixth Avenue) or Seventh Avenue and Chelsea to the west; 25th Street and NoMad to the north; Rose Hill to the northeast, and Lexington Avenue/Irving Place, Gramercy Park to the east.
Broadway cuts through the middle of the district, and Madison Avenue begins at 23rd Street and runs north. At the north (uptown) end of the district is Madison Square Park, which was completely renovated in 2001.
Gramercy is located on the East Side, from 14th Street to 23rd Street, from Park Avenue South to the East River.
If you’ve ever wanted a secret garden to call your own, the co-ops and townhouses for sale and rent alongside Gramercy Park are for you. The entire little enclave of Gramercy is the brainchild of a nineteenth-century real estate developer who created one of New York City’s most beautiful green spaces — a private park — and then built apartments and row houses with views of it. To add to the prestige, these wonderful homes come with keys to the gated oasis that’s Gramercy Park — it only opens to the public once or twice a year.
Many of these renovated townhouses along Gramercy Park, with their mahogany and marble details and their fine gardens, can best be called mansions. The surrounding area of Gramercy has some row-house character too, but also contains large apartment buildings with all the modern conveniences. The new Gramercy by Starck condo, for example, has a doorman — but it also has library lounge with fireplace and a screening room as well as a luxury outdoor deck with cabanas.
